Hi guys, I'm trying to figure out what model this quad is, and where I could get a replacement exhaust pipe / muffler. Here is what I know. It is 90cc. It is older than 2007. It has the VIN under the seat and the number is LAGAKUCY041002727. IMG_4213.jpgIMG_4219.jpgIMG_3412.jpgIMG_4216.jpgIMG_4217.jpg
